`PARLOR HEATINGQSTOVE.

SPECIFICATION forming part of Letters Patent No. 311,139, dated January 20, 1885.

y .ippliwion aniram-i113, less. (No monti) portion-of the heat generated is delivered by register into an upper room but this may be dispensed with and the entire heat of the stove radiated within the room in which it is placed.

`The object of the invention is to increase the heat-radiating capacity of the stove by additional cold air jackets and pipes placed exterior and interior of the stove-case. The general outline of the stove is as shown in the 2o perspective view, and a horizont-alcross-sec-V tion would be square or rectangular.

In the accompanying drawings, forming a part of this specification, and in which simi# lar letters indicate similar parts, Figure l, 2 5 Sheet l, is a perspective elevation of the stove.

Fig. 2, Sheet 2, is a vertical sectional view of the same. Fig. 2, Sheet 2, is a partial section, showing a register in lieu ofthe hot-air pipe for an upper room. Fig. 3, Sheet 3, is a 3o horizontal section at aa of Fig. 2, showing the magazine, draft-dainper, and revertible iiue and hot-air pipe. Fig. 4, Sheet 3, is a horizontal section at b b of Fig. 2, showing magazine, cold-air ducts, hot-air drum, revertible nue, and cold-air jackets. Fig. 5, Sheet3, is a horizontal section at C C of Fig. 2, showing the upper fire-pot, the combustionchainber for same, air-jackets and air-tubes, and the grate of the lower nre-pot and dust-line. Fig. 4o 6, Sheet 3, is a horizontal section atd cl of Fig.

2, showing the ash-pit and the external airjackets and the internal cold-air pipes and dust-flue. Fig. 7, Sheet 3, shows a horizontal section at e e of Fig. 2, giving the arrangement of the base for cold-air chambers, and showing the air-jackets. Fig. 8, Sheet 4, is a sectional elevation, designed to show more clearly the working of the stove as a cold-base and airjacketed heater, in all of which noting only 5o the parts that pertain toA the cold-base and cold-air jacketed stove.

P P P, cold-air pipes interior to the stove; R, main damper; R', don1e-plate damper; R2, damper to thel dust-flue', S S, partitions dividing the hollow base into cold'air chambers; T, the fdust-iiue carried up between the cold-air jackets N N from the ash-pit into the uptake. U 1is a revertible flue from the dome" to the up take. V are apertures from the hot-air drums into the hot-air reservoirs; V V, hot-air drums; V2, cold-air edncts from the frontof the stove .into the hot-air drums; W, register in top plate of hotair reservoir.

The stove may be operated both as a direct or inverted draft heater, also as a singleI or double heater. Ve will first operate it asa direct-draft stove. The magazine is suspended by a flange from theV dome-plate, and drops, clear ofthe case inside of the stove, to within about three inches ofthe upper firepot, H, and is provided with fingers at its front and rear lower ends. The upper fire-pot, H, is suspended from the case, and projects downward to within about three inches of the lower nrepot, and is also provided with ngers on its lower front edge. The lower repot, G, rests, as is usual, upon the grate-frame suspended in the ash-pit, and is provided with a La Rue or equivalent cleaninggrate. Combustionchambers K K are formed at both fire-pots, and the products of combustion from the lower iire-pot, G, and chamber K are drawn up through the incandescent fuel of the upper repot, H, and, together with the products of combustion therefrom in thechamber K, circulate around the magazine I and against the sides of the hotair drums V V, next to the magazine, and, according to the manner in which the damper R in the uptake L and R A represents the base or ashpit section; B.

in the dome-plate operated, will pass directly into the uptake-flue L, or, passing into the dome, will revert down the flue U on the opposite side, and thence into the uptake. The pipes l? may also be used in combination with the exterior cold-air jackets, thus increasing the circulation of air through the stove and increasing the radiating effect of the same.

The cold and heated air circulates as follows: Where the air-jacket is used, the heating of the back of the stove, rarefying the air within the jacket, causes the same to rise, which induces the colder currents of 'air near the floor to rise within the fines N N, and from there pass into the hot-air reservoir M, and from thence up the pipe M into the room above. The cold air also entering at the front of the stove is caused in the same way to rise into the hot-air drums on the right and left of the magazine, and after being heated is passed through apertures V V in the back of the case into the hot-air reservoir M. A register placed between the stove and the hot-air pipe M permits a portion of the heat generated to pass into the lower room, and, it' the hot air is not required for an upper room a register will take the place of the pipe h and the circulation of air through the room may be regulated thereby. Vhen the pipes l? are put into service, the air within the same is rapidly heated, and a corresponding force given to the entering and discharged air therefrom. This is occasioned by their passing through both ofthe combustion-chambers. These pipes may be of Wrought or cast iron. rlhe maga zine being suspended by its flanges alone with a clear space of one or more inches between it and the sides of the hot-air drums V V, its expansion and contraction throw no strains upon the stove, and do not rack the joint as when secured to the casing of the stove. The front and sides of the stove are provided with a double row of illuminatingwindows, which correspond with the spaces between the magazine and upper iire-pot, and between the upper and lower re-pots, giving at all times a bright and cheerful appearance to the stove.

We are well aware that we are not the rst to place air-j ackets exterior to a heating-sto ve, or to place cold-air pipes within a stove; but we believe ourselves to be the first to place air-jackets exterior to a stove in combination with heating-drums placed in the combustionchamber ot' the stove, and having a hot-air reservoir common to both. We also believe ourselves to be the first to make use of coldair pipes interior to the stove and passing through two combustion chambers therein. We also believe ourselves to be the iirst to use superimposed fire-pots in a stove of a square or rectangular cross-section.

We lay no claim to the use ot' double tirepots per se in stoves of square cross-section, they having been used in combination with stoves of a cylindrical crosssection for many years.

Having described our improvement and shown its construction and operation, we desire to secure by Letters Patent the following claims:

l. The combination ofthe'combnstion-chamber K, and the heating-drum V within the same, with a magazine freely suspended in said coinbustionfchamber, the heated products of combustion circulating around the maga- Zine and impinging upon the interior surface ofthe drum, said drum provided with inlets V`l and outlets V, as shown, and for the purpose set forth.

2. The combination of the following ele- So ments: the heating-drum V, having the inletducts V2 and exit-openings V, the hot-air reservoir M, having register W and hot -air pipe M', and the air-jacket N, substantially as described.
